A police probe the disappearance and death of Kaiga nuclear power plant scientist L Mahalingam, his family on Monday demanded that a DNA test be done to establish his identity.
On the basis of the dress worn by Mahalingam, his wife Sundari and brother Indrajit had identified the body, which was handed over to the family yesterday after post-mortem and cremated.
But Indrajit has now petitioned the police asking for the DNA test on the grounds that the decomposed body fished out from Kali river on June 13 night was beyond recognition, police sources said.
Police, meanwhile, today arranged for taking blood samples of Dhakshayayini, mother of 47-year-old Mahalingam.
It is suspected that the body of Mahalingam remained in water for about four days after he went missing under mysterious circumstances on June eight.
Uttara Kannada Superintendent of Police Raman Gupta refused to share details of the ongoing investigation.
"We can't say anything till we get the complete post mortem reports and chemical analysis of viscera to decide whether it is a case of suicide or murder".
The body of Mahalingam was recovered by navy divers from the Kali river which runs along the Kaiga township. Earlier, during his stint at Kalpakkam atomic power plant near Chennai also he had gone missing but returned home after a few days.
Interestingly, police are yet to get leads in another murder case in which Ravi Moole, also an employee of the Kaiga plant, was allegedly murdered about a month ago.
